RATCHET-WBENCH.

Specification of Letters Patent.

Patented Jan. la, it.

Application led June 18, 1912. Serial No. 704,300.

To all 107mm it lmay concern.'

Be it known that @Le SrnNnnseN, a citizen of the United States, andresiding at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful improvements in Ratchet-WTrenches, ofwhich the following is a specification, such as will enable thoseskilled in the art to which it appertains to make and use the same.

This invention relates to wrenches, and particularly to what are knownas ratchet wrenches, and the object t-hereof is to provide an improveddevice of this class which is simple in construction7 convenient ofoperation, and which is provided with adjustable and reversible jaws soformed as to adapt the device for use, either as an ordinary ratchetwrench or as a pipe wrench, and with this and other objects in view theinvention consists in a wrench of the class specified constructed. ashereinafter described and claimed.

The invention is fully disclosed in the following specification of whichthe accompanying drawing forms a part, in which the separate parts of myinvent-ion are designated by suitable reference characters in each ofthe views, and in which Figure l is a sectional side elevation of myimproved wrench; Fig. 2 a transverse section on the line 22 of Fig. l;Fig. 3 a sectional plan view on the line 3 3 of Fig. l; Fig. a a planview of the head of the wrench with the handle in position; Fig. 5 abottom view of the head portion of the handle, and Fig. G a section onthe line 6M@ of Fig. 4.

In the practice of my invention, I provide an oblong head block a inwhich is a longitudinal chamber a2 rectangular in cross section and theside walls of which are provided with inwardly directed flanges as atthe bottom of said head and which form a central longitudinal openingwhich communicates with said chamber throughout its length, and theouter end of the chamber a2 is closed by a wall and mountedlongitudinally in said chamber is a screw shaft o provided with reversethread b2. One end of the shaft b is provided with a bearing in the endwall at of the chamber a2, as shown at b3, and the other end thereof isprovided with a milled head b4 detachably mounted on said end of saidshaft and held thereon by a nut d5, and in practice, the shaft Z) isturned by means of the head Z2". I also provide two similar jaw members0 having rectangular heads c2 movable in the chamber a2 and throughwhich the Ashaft b passes, and by turning said shaft the jaws c may beadjusted toward or from each other according to the direction in whichsaid shaft is turned. The jaws c are provided on one side with straightfaces c3, and when said jaws are in the position shown in Fig. l, thedevice may be used as an ordinary wrench, or as a monkey wrench, and theopposite faces c4 of said aws are inclined, and provided with ratchetteeth, and by reversing the position of said jaws in the head block athe device may be used as a pipe wrench, as will be readily understood.

rlhe head block ais provided centrally of the top thereof with a ratchete which may be formed integrally therewith or secured thereto, and abovethe ratchet e is a cylindrical stud f, on which the handle g is mounted,said handle being provided with a head g2 having a countersunk plate gqthrough which a screw g4 is passed into the stud f, and thisconstruction securely binds the handle g to the stud f and to the headblock a, as will be readily understood, and the bottom of the head ofthe handle is provided with a circular chamber g5 in which the ratchet eis rotatable, and it will be understood that in the operation of thedevice the head block a turns with the ratchet e and stud f, or saidratchet and stud turn with said head block.

Countersunk in the bottom of the handle g and in the wall of the head g2thereof is a plate 7L which is secured to the handle by screws h2, andin the top surface of the plate It are longitudinal grooves or spaces c'which diverge in the direction of the ratchet e, and in which aremounted longitudinally movable and rotatable blocks y' between which andthe outer end of the grooves or spaces t' are placed spiral springs 2,and said springs bear on the blocksj and normally force them in thedirection of the ratchet c, and the blocks j are provided with nosepieces jg which operate in connection with the teeth of said ratchet.

Formed in the top of the head portion of the handle adjacent to the studf and plate g3 is a transverse recess 7a at the ends of which arelongitudinal. recesses 7a2 which comn'iunicate therewith and whichdiverge in the direction of the said stud and plate, and the blocks jare provided with headed pins jg which pass through said recesses 7a2,and by means of which the blocks may be moved baclwardly against theoperation of the springs 2, and when said blocks are in their rearmostposition, the pins j may be turned inwardly into the recesses 7c, asshown at the right of Fig. 6, so as to hold the blocks out of engagementwith the ratchet e.

The operation of this device as a ratchet wrench is similar to that ofother devices of its class. illhen the blocks are in the position shownin Fig. 4f, the handle is locked and the wrench cannot be operated, butwhen the blocks are in the position shown in 6, the handle may beoperated, as will be readily understood, and the wrench manipulated forthe desired purpose, and with the bloclrs j in the position shown in (3,the first movement of the handle is in the direction of the arrow ofFig. 8. and by swinging said handle bael: and forth, the head bloelr aand the aws o may be turned in the direction of the arrow fr, as will bereadily understood, but by reversing` the position of the blocks .7' thefirst movement of the handle g will be inl the direction of the arrow032 in Fig. 8, and by moving said handle baclr and forth in the usualmanner the head block a and jaws c may be turned in the oppositedirection.

From the foregoing description it will be seen that my improved wrenchis comparatively simple in construction and operation, and will noteasily get out of order and said wrench may be used either as anordinary wrench, as a monkey-wrench, or as a pipewrench, and the jaws cin either position may be easily adjusted toward and from each other bysimply turning the shaft 7), by means of the milled head b thereof.

Having fully described my invention what claim as new and desire tosecure by Letters Patent is;be

l. in a wrench of the class described, a head block provided with acentral oblong chamber rectangular in cross section and the bottom ofwhich is provided with a longitudinal opening which communicates withsaid chamber, two jaws having rectangular heads which iit in and aremovable longitudinally of said chamber and are entirely inclosedtherein, and a shaft passed longitudinally through said chamber and theheads of said jaws, said shaft being provided with reverse threads andthe heads of said jaws being correspondingly threaded whereby theturning of said shaft will adjust said jaws into different positions.

2. 1n a wrench of the class described, an oblong head block providedwith a ratchet above which is a cylindrical stud, and a handle the headof which is mounted on said stud and rests on said block, said handlebeing provided with a chamber in which said ratchet is adapted torotate, and said handle being also provided with longitudinal chambersor spaces which open upwardly through the top thereof and in which aremounted spring-operated blocks having nose pieces adapted to engage saidratchet at opposite points, and handle pins connected with said blocksand extending upwardly through said handle and by means of which saidblocks may be moved away from said ratchet, said handle being alsoprovided in the top thereof and at the outer' end of said chambers orspaces with transverse recesses into which said handle pins may beturned so as to loclr said blocks out of engagement wit-h said ratchet.

In testimony that I claim the foregoing as my invention l have signed myname in presence of the subscribing witnesses this 17th day of June1912.

OLE STENERSEN.
